The New York Daily News casts a spotlight on Ray Felix, the small-press publisher who's challenging the joint claim of DC Comics and Marvel to the "super hero" trademark, and comes away with some interesting details:

• The two publishers have prevented at least 35 people from using "super hero," or some variation, since they were granted the mark in 1980 for toys and in 1981 for comic books. (You may remember that in 2004 GeekPunk changed the name of its series Super Hero Happy Hour to Hero Happy Hour following objections by DC and Marvel.)
• Although Felix admits he's unlikely to win his case before the Trademark Trial and Appeal Board, a lawyer specializing in intellectual property tells the newspaper that Marvel and DC's joint ownership "violates the basic tenet of trademark law." "A trademark stands for a single source of origin, not two possible sources of origin," Ron Coleman argues. "If the public understands that the word 'superhero' could come from A or B, then by definition that's a word and not a trademark."
• Even if the appeal board were to find in Felix's favor, it would only mean he can retain his registration for his series A World Without Superheroes. Revocation of Marvel and DC's trademark would require a costly civil lawsuit.

Felix's dispute with the comics giants dates back to September 2010, when he received a cease-and-desist letter after registering a trademark for his series. Following more a year and a half of exchanges between Felix and the companies’ attorneys, DC Comics and Marvel Characters Inc. in March 2012 filed a formal opposition with the Trademark Trial and Appeal Board.
